You are likely to have a large collection of contacts that are a mix of Capitalised names, partially capitalised names, too many first names, etc. It would be great if you could do a filter search and create style format that automatically updates like this:

All contacts to be corrected to be [First] [Last]

Equally - if someone was saved with their full name under 'First' - that would be a great filter to try and then fix that.
